-itis

(Greek: a suffix; inflammation, burning sensation; by extension, disease associated with inflammation)

This suffix has come to mean "inflammation of" but originally it meant "pertaining to" or "of the". The Greek word nosos ["disease"] was either expressed or understood, although it might not be included with the basic element. For example, bursitis nosos would mean "disease of the bursa".
